Symptoms During or Shortly After Isolated Carpal Tunnel Release and Problems Within 24?hours After Surgery

This study used the National Survey of Ambulatory Surgery (NSAS) database to measure the incidence of and risk factors for symptoms in the ambulatory surgery center and problems within 24 h after isolated carpal tunnel release (CTR). The NSAS contained records on 400,000 adult patients with carpal tunnel syndrome who were treated with CTR in 2006, based on ICD-9 codes. The type of anesthesia used and factors associated with symptoms and problems were sought in bivariate and multivariable statistical analyses. The mean duration of the procedure was 16 ± 8.8 min. Only 5 % were performed under local anesthesia without sedation, 45 % with IV sedation, 28 % regional anesthesia, and 19 % general anesthesia. Symptoms in the ambulatory surgery center or a problem within 24 h after discharge were recorded in 10 % of patients, all of them minor and transient, including difficulties with pain and its treatment. The strongest risk factors were male sex, age of 45 years and older, and participation of an anesthesiologist. Local anesthesia and regional anesthesia were associated with more perioperative symptoms and postoperative problems. Most CTR are performed with some sedation in the United States. CTR is a safe procedure: one in 10 patients will experience a minor issue in the perioperative or immediate postoperative period.     

椎弓根螺钉三椎体内固定对脊椎爆裂性骨折患者椎体与神经功能状态的影响观察

目的:探讨椎弓根螺钉三椎体内固定对脊椎爆裂性骨折患者椎体与神经功能状态的影响.方法:选取2013年7月至2015年1月于本院进行治疗的58例脊椎爆裂性骨折患者为研究对象,对其进行回顾性研究,将其根据手术方式不同分为对照组(短节段椎弓根内固定组)29例和观察组(椎弓根螺钉三椎体内固定组)29例,然后将两组患者手术前与手术后不同时间的伤椎恢复指标与血清神经功能相关指标进行比较.结果:观察组手术后不同时间的伤椎恢复指标中的后凸Cobb角、椎体平移率、椎体高度丢失率与血清神经功能相关指标中的BDNF、NSE、NGF及S100B均显著好于同期的对照组指标,并且明显好于其治疗前,均有显著性差异(P＜0.05).结论:椎弓根螺钉三椎体内固定可更为有效地恢复脊椎爆裂性骨折患者椎体参数,并且更有助于神经功能状态的恢复.     

经皮椎体后凸成形术治疗胸腰椎骨折的临床疗效观察

目的：探讨经皮椎体后凸成形术治疗胸腰段椎体压缩性骨折的临床疗效.方法：2003年6月～2005年9月收治74例胸腰段椎体压缩性骨折患者,根据手术方法不同分为A组（椎体后凸成形术组,24例）和B组（椎弓根螺钉固定组,50例）.比较两组术前术后椎体前缘、中线、后缘高度变化,疼痛视觉模拟评分（visual analogue pain scale,VAS）,手术时间,出血量等方面的差异.结果：两组对椎体高度的恢复比较无统计学意义,A组的手术时间和出血量较B组少,差异有统计学意义（P＜0.01）,术后VAS评分A组较B组低（P＜0.01）.结论：经皮椎体后凸成形术与椎弓根螺钉系统治疗椎体压缩性骨折具有相似效果,但经皮椎体后凸成形术具有创伤小、手术时间短、出血量少等微创优点.
